[Once again, you arrive at the northwest back door of Daxuan Royal Palace and patiently wait.]
[Two hours later, you finally see the back door open, and you quickly capture all four guards. You then search for their marks on their bodies with the help of the Skywolf Clan Great Princess.]

[One minute later, relying on the mark, you take on the appearance of the guard and successfully enter the palace.]
